Description OSIDB Bzimport 2025-05-01 14:03:29 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: openvswitch: fix nested key length validation in the set() action

It's not safe to access nla_len(ovs_key) if the data is smaller than
the netlink header.  Check that the attribute is OK first.
